These were a huge hit! They tasted and looked great! They are, however, labor intensive. Marinating the cheese is easy but slicing the olives takes a lot of work. Finding un-pitted green olives wasn't easy and I had to buy them at Whole Foods. Also, cutting through the green olives with a straw was very tough indeed. Something like a narrow metal tube or pipe might work better. The plastic just didn't cut through the olives well at all. Similarly, cutting off the ends of the green olives was tough as well since the flesh clings to the pit. The variety of green olive may have made a difference since I grabbed the one and only type of unpitted green olive they had. Other varieties might be easier.
When setting up the eyeballs, make sure to set them a bit askew from one another so it looks a bit randomized. If they're all perfectly facing the same direction, it doesn't look as real.
